PAPER-REGISTERING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 648,161, dated April 24, 19O.

Application led February 24,1899. Serial No. 706,704.. (No model.) l

TortZZ whom t may concern.-

Be it knownvthat I, TALBOT O. DEXTER, a citizen of the United States, and a resident of Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of registering instruments which are equipped with a point or tongue entering or engaging a` slit or perforation previously made in the paper for that purpose, said engagement arresting the motion of and thereby registering the sheet while carried to a position to be folded or otherwise operated upon. Such register'- inginstru ments are chiefly employed on paperfolding machines and have hitherto been placed over the path ofthe paper and usually cooperated with a bridge disposed under the path of the paper to open the slit therein, so as to facilitate the entry or engagement of the registering-point. Said arrangement of the registering instrument in relation to the path of the paper necessitated the placing of the slit-opening bridge with its abrupt and high end facing from the paper-folding' rolls, and in order to prevent said end of the bridge from catching on thev edge ofv the slit andthereby tearing the sheet in the operation of introducing said sheet between the folding` rollers it was necessary to employ a cam formed with two successive steps or other suitable mechanism to impart to the register-V ing instrument two successive lifts, one of which caused theentered registering-.tongue to lift the slitted portion of the paper over the bridge, and the second lift raised the reg- Y istcring instrument still farther to permit the front end of the next incoming sheet to freely pass under the aforesaid registeringtongue. The most serious defect of such operation of the registering instrument is theliability of- Aa plan view of the same.

essentially, in the combination, with paper-y conveyers, of a registering instrument dis-l posed beneath the path of the paper and provided with a point for engaging a slit in the paper and periodically-operated means for forcing said pointvinto engagement with the slit in the paper in transit; and the inventionalso consists in novel construction and combinations of auxiliary devices connected therewith, as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a paper-folding machine equipped with my improved registering instrument. Fig. 2 is an enlarged side elevation of said registering instrument. Fig. 3 is Fig. 4 is a further enlarged perspective view yof the sheet-depressing foot. Fig. 5 is a plan view of said foot and subjacent registering instrument. Fig. 6 is a transverse section on line x in Fig. 5. Fig. 7 is a side elevation of a modification of my invention.

Referring'to Fig. 1 of the drawings, A represents the main supporting-frame of a paperfolding machine.

RR are the paper-folding,rollers; B, the blade which introduces the paper between said rolls; C, the feed-roller.; a, the paper-L conveying tapes which carry thefpaper from the said feed-roller to the folding-rollers.

One of the drop-rollers is placed over the feeding-roller.

h designates the stationary longitudinal bars which support the paper beyond the folding-rolls. l p

D denotes the front stop which arrests the paper carried into the machine by the aforesaid t-apes. This front stop is in the present case arranged to alternately advance to and recedefrom its sheet-arresting position and is actuated by mechanisms similar to those shown in my Letters Patent No. 561,937, dated June 9, 1896, in which said front stop is termed the first-fold gage. Said front stop or gage rides on a longitudinal bar c, which is supported at one end on a roller F and is attached at the opposite end to a bracket c', pivotally .connected to the end of an arm c2, which is fastened to a rock-shaft c3, extendtion; and to that end the invention consists,

IOO

.ion cl3, engaged with a similar wheel d, at-

` stop is necessary to accommodate it to different-sized sheets of paper fed to the machine.

In the Letters Pat-ent hereinbefore referred to and in other prior Letters Patent the paperregistering instrument is arranged above the stationary paper-supporting bars b and cooperates with a stationary slit-open ing bridge which necessarily was placed with its high and abrupt end facing toward the front stop D. Said disposition of the bridge is liable to cause it to catch on the edge of the slitted portion of the paper and tear the paper when drawn toward the folding-rolls R R by the folding-blade B tucking the paper into the bite of said rolls. To guard against such accident, it was necessary to employ means for imparting two successive lifts to the registering instrument after the registering of the paper had been perfected7 and for this purpose a rotary cam formed with two steps of dil'erent radii was employed to impart two successive lifts to the arm which carries the registering instrument. The first of said lifts was necessary to lift the slitted portion of the paper by the entered tongue sufficiently to carry the said portion of the paper over the bridge, and the second lift was required to afford clear passage of the next incoming sheet under the registering instrument. In the operation of said registering instrument it has been found that the lifting of the paper over the bridge after the registering of the paper has been perfected is liable to disturb the paper from its registered position. These defects are overcome by my present invention in placing the registering instrument under the path of the paper and employing in connection therewith suitable periodically-operated means for forcing said instrument into engagement with the slit in the paper in transit, in connection with which registering instrument I preferably employ auxiliary devices, as hereinafter described. f denotes said registering instrument, consisting of a point or tongue formed on a blockf", which is mounted adjustably on a suitable vertically-movable support, for which I prefer to employ a longitudinal bar g, arranged between two stationary longitudinal paper-supporting'bars h and pivotally connected at each end to one of the arms of one of the bell-cranks t, pivoted to one of the stationary bars h. The other arms of said bell-cranks are connected by a rod t" and receive aproperly-timed oscillatory motion, as hereinafter described, to periodically lift the registering instrument to a position to register the paper in transit. Said registeringinstrument projects from the block f slightly upward and toward the folding-rolls, and under the registering-pointf is a tongue f2, projecting likewise from the block f', said tongue serving to support the slitted portion of the paper while the registering-point]C enters into the slit in the paper. The tops of the block f and registering-pointjare sloped or inclined from the folding-rolls or toward the front stop D, so as to allow the paper to freely slide over them and the paper to be withdrawn from the registering instrument by introduction ofthe paper into the bite of the folding-rolls. There are two of such registering instruments located at opposite sides of the longitudinal center of the path of the paper, and directly over each of said instruments is a sheet-depressing foot O, depending from and rigidly attached to a bracket N, mounted on a longitudinal rock-arm P and adjustably secured in its position by means of a screw n, journaled on said arm, as shown at n', and passing through a nut n', affixed to the bracket n. A suitable knob or thumbpiece n2 is attached to the end of said screw for turning the same.

The corresponding adj ustability of theregistering instrument is illustrated in Fig. G of the drawings, and consists of the blockf, sliding in longitudinal ways o o in the bar g and clamped in its required position by means of a screw o', inserted into the block from underneath,and a spring-plate o2, interposed between the head of said screw and under side of the bar g.

The sheet-depressing foot O is provided with a slot O', as shown in Figs. 4 and 5 of the drawings, for the protrusion of the registering instrument when lifted to its operative position. Said shoe is thus caused to depress the sheet at opposite sides `of the registering instrument.

The foot O is depressed simultaneously with the lifting of the registering instrument by means of mechanisms which I will now describe.

The arm P is pivoted to a bracket J, which is mounted on a stationary cross-bar K and adjustably secured in its position by means of a horizontal screw J', passing through a screw-threaded ear on the bracket and provided with suitable means for turning it by hand and thereby shifting the bracket length- `wise on the cross-bar.- The pivoted end of the arm P is formed with an upward extension P, the upper end of which is connected bya rod j to an arm j', attached to a shaft Z, which is mounted on a bracket J and receives intermittent rocking motion from a lever Z, attached to said shaft and bearing with its vfree end on a single stepped cam U, attached to IOO IIO

648,161 v v e to the shaft of the cam H. To the shaft Z is also attached an arm r, the free end of which is connected by a pitman r' to one'of the bellcrank arms t, to which the rod t" is connected, as .hereinbefore described.

The modification of my-invention shown in Fig. 7 of the drawings consists in the form of the sheet-depressing foot O, Which in this case is integral with the arm P and extends toward the folding-rolls R.

The operation of myinvention is as follows The registering instrument f is lowered beneath the path of the paper, and the paperdepressing foot O is raised while the paper is carried into the machine-by the tapes a. The front stop D is at the same time in its nearest position to the folding-rolls R R to arrest the advance movement of the sheet. The sheet is then registered laterally by any suitable and Well-known means, (not shown,) and as soon as this is eifected the two feet O descend to gently bear on the sheet, and at the same time the registering instruments frise and the :front stop D recedes kfrom its sheet-arresting position and allows the sheet to be advanced by the tapes a. During this movement of the sheet the registering-points f project slightly above the plane of the papersupporting bars h and bars h to allow said points to enter into the slits in the sheet. The edges of the slitted portions coming subsequently in contact with the shoes f,be-

tween the pointsf and tongues f2, arrests the paper in its registered position. As soon as this is accomplished the sheet-depressing feet O rise to the position shown in Fig 2 of the drawings, and then the folding-blade B descends and tucks the paper into the bite of the folding-rolls. In the resultantdraft of the sheet to the folding-rolls the slitted portions of the sheet slip freely out from between the registering-points f and subjacent tongues f2, while the sloping tops of the registering instruments permit the sheet to freely slidev over them without danger of tearing or injuringthe sheet or disturbing it from its regist-ered position.

It will be observed that the herein-described sloping block f', with the correspondinglysloping registering-point f, projecting from the high end of said block and disposed-beneath the path of the paper, constitutes a combined slit-opener and registering'instrupoint, and periodically-operated means for forcing said point into engagement With the slit in the paper in transit.
